An examination of the Copper Hoards artifacts shows that they were made both by hammering and cutting metal sheets, as well as by closed casting. A small percentage of the artifacts (Fig. 5) show lead alloying, probably for better fusibility. Metallographic examination of the artifacts indicates slow cooling, cold work, and annealing.
